The TZ727 wireless GPS dog fence collar delivers dependable containment without recurring fees, subscriptions, or app requirements. This advanced system establishes customizable safe zones from a minimum radius of 33 yards to a maximum of 1000 yards (approximately 0.7-650 acres), adapting to your property's layout. Engineered for dogs weighing 10–120 pounds, the color screen display provides clear, real-time feedback on boundary status and collar function. The wire-free design eliminates installation complexity while maintaining reliable performance. Ideal for pet owners seeking straightforward, cost-effective boundary management with no hidden charges or connectivity dependencies.

TZ727 GPS wireless dog fence is equipped with an advanced U.S.-made GPS chip and an enhanced AI algorithm, delivering stronger anti-interference capability, sharper sensitivity, and smarter detection. It precisely tracks your dog’s real-time position and guides them to stay within the set boundaries, ensuring your pet remains safely inside the designated outdoor zone.

To promote safe habits, the system delivers mild, step-by-step corrections—sound, vibration, and/or static stimulation (up to 6 levels)—as your dog nears the preset boundary. If your dog keeps moving beyond the limit, the collar switches to a safety mode after two correction cycles, preventing excessive stimulation and ensuring a humane, pet-friendly training experience.

Built for wide-open environments, this system lets you set a customizable circular boundary with a radius from 33 to 1000 yards—covering anywhere between 0.7 and 650 acres. It’s an excellent fit for farms, spacious properties, and open landscapes. Though not suited for small yards, heavily wooded areas, or indoor use, the system automatically reactivates once your dog returns to a clear outdoor space.
